LOOP SLIDE BUCKLE Filed Aug.'l4, 1930 JEN-1N H DEIMKEE Patented Apr. 28, 1931 STATES JOEN H. DOMKEE, OF WEST HAVEN, CONNECTICUT, ASSIGNOR TO THE WIRE NOVELTY IMANUFACTUBING COIMIPANY, OF WEST HAVEN, CONNECTICUT, A CORPORATION OE CONNECTICUT LOOP SLIDE BUCKLE Application filed August 14, 1930. Serial No. 475,164.

This invention relates to loop slide buckles combining a button loop with a slide buckle adapted to be adjustably mounted upon a strap from which the device is suspended for a connective engagement with a button provided by a garment, or the like, thus supported by the strap. The usual type of combined button loop and slide buckle employs a button loop of rigid or expansible structure that provides associated buttonreceiving and button-retaining loops with an intermediate contracted throat portion,

a button first being received in one loop and urged into the other loop against the tension of the throat portion expanded, in an expansible loop, by the passage in the button shank therethrough. The novelty of this invention however includes a structure that provides but one button engaging loop into which the button is both received and retained, and the objects of the invention are to provide a button loop structure having a single button engaging loop to receive and retain a button; to provide an expansible button loop structure having a button retaining loop formed by the structure terminals held contracted by a strap suspension member carried thereby and under a pulling strain; to provide a button loop structure connectible with a button by a mere plunging movement or the loop structure along the plane thereof and against the shank of a button; and to provide a button loop of such structure that, to disconnect a button retained therein, the retaining-loop structure is merely pulled away from the button in the plane of the loop. With these and other objects in view as may become apparent from the within disclosures, the inven tion consists not only of the particular form herein pointed out and illustrated in the drawing, but readily admits of certain modifications within the scope of what hereinafter may be claimed.

The character of the improvement may be best understood by reference to one illustrative device embodying the invention and illustrated by the accompanying drawing in which the Figure 1 is an upright elevation of the device, the parts being in such relative positions as to maintain a rigidly closed button shank entrance; the Figure 2 is a similar upright elevation to that in the previous figure, excepting that the parts are relatively positioned so as to permit an expanded entrance; the Figure 3 is an upright elevation of the device as illustrated in the next previous figure, excepting that the entrance is expanded; and the Figure 4 is a side elevation of the device, the Figure 5 being an upright elevation of a slightly modified device.

Referring more particularly to the drawing the device is made in two parts of which one is rigid and the other being resilient. The rigid member 1 of the device is pret erably made from sheet metal although it may be made of wire if so desired. A loop portion 2 of the member 1 is stamped to provide the top horizontal bar 3 with a series of teeth t directed within the'loop 2, the lower portion of the rigid member 1 is shaped and formed into a loop 5 elongated in the plane parallel to that of the bar 3, the enclosing ends of the loop 5 relatively converging downwardly. The member 6 is made of resilient wire, a middle portion or which is bent to form the loop 7 with the top horizontal bar 8, and depending from the loop 7 the remaining wire portions are relatively converged downwardly, as at 9 and 10, and the wire terminals are then formed so that together they provide the button engaging loop 11 having the interior cam surface 12 and the exterior cam surface 12 on each side of the entrance 12. The members 1 and 6 are assembled by inserting the relatively convergent portions 9 and 10 of the member 6 within the elongated loop 5 for a limited relative sliding movement therein.

The device is mounted upon the suspended strap S, as illustrated by the Figure l, so

that the strap enters the device between the v teeth 4 and the bar 8 around which the strap is looped to extend between the bar .8 and he lower portion of the loop 2, the free end of the strap depending therefrom at the rear of the device. An upward pulling resilient y strain upon the strap, thus engaged with the teeth a of the rigid member 1, and a downward pulling strain occasioned by a button retained within the loop 11 and transmitted to the resilient member 6, the relative positions of the device members 1 and 6 are such that the relatively converged portions 9 and 10 are bindingly held within the loop 5 to such an extent that the entrance 12 to the button engaging loop 11 is maintained rigidly closed, as illustrated by the Figure 1, even as against the pulling strain thereon by said button. Regardless of such pulling strain in opposite directions upon the members 1 and 6, the button may be released by the manual lifting of the resilient member 6 from under the loop 7 to the position illustrated by the Figure 2 wherein the relative convergent portions 9 and 10 are left free to expand within the elongated loop 5 to either permit the shank S of a button to enter or leave the loop 11 by cam operating the loop entrance 12, as at 12 or 12', respectively. To connect the device with a button, the exterior cam surfaces 12" are pressed against the shank S of a button by a plunging movement along the plane or" the device thereagainst with suliicient force to expand the entrance 12 to an open position as illustrated by the Figure 3.

The Figure 6 illustrates a slightly modified structure of which both members 1A and 6A are made of wire. The structure of the resilient member (3A is identical with that of the preferred form of the member 6. The rigid member 1A is of wire formation of which the lower part provides the elongated loop 5A slidingly holding the relatively convergent portions 9A and 10A therein, and the upper part provides a loop 7A slidingly mounted upon the structure of the loop portion 2A. In mounting the modified form of device upon a strap, such strap would be looped around both of the top bars and 8A, the bar 3A standing the strain in an upward pulling direction.

I claim:

1. A loop slide buckle comprising a resilient wire of which a middle portion is bent to form a loop having a top horizontal bar, side bars and aligned lower bar sections, the remaining wire portions relatively converging therefrom downwardly and the wire terminals together forming a button engaging loop with a normally contracted entrance having interior and exterior cam surfaces; and an associated rigid slide buckle member having a loop portion encompassing the converging portions for a limited relative sliding movement therein, the rigid member including a loop having a strap engaging bar flattened in the plane of the member and provided with a series of teeth extending into the rigid loop, the aligned lower bar sections of the resilient member being positioned below the strap engaging loop of the rigid member.

2. A combined button loop and slide buckle comprising rigid and resilient members, the rigid member comprising a suspension loop having a top horizontal bar for strap engagement and also having a depending loop elongated in a plane parallel to said bar; and the resilient member having a loop with a top horizontal bar, positioned adjacent the other bar, and also having a depending button engaging loop with a normally contracted entrance provided with interior and exterior cam surfaces, the resilient member being intermediately provided with relative converging portions held within said elongated loop for a limited relative sliding movement therein to either hold said entrance contracted or to permit an expansion thereof.

A combined button loop and slide buckle comprising a rigid member having a susoension loop providing a bar for strap engagement and a rigidly depending elongated loop lying in a plane parallel to said bar; and an associated resilient wire loop member having relatively converging portions held within said elongated loop for a limited sliding movement therein, the resilient wire loop member including a button engaging loop with a normally contracted entrance having interior and exterior cam surfaces, the resilient member having aligned shoulders positioned below the rigid suspension loop.
